To all whomit may concern I Be it known that I, HENRY G.-KanR, ,a

citizen of the United States, residing at. r

Roanoke, in the county of Roanoke and State of Virginia, have invented a new and useful Car-Coupling, of which the followin is .a specification.- I

' t is the object of thepresent invention 1 to provide an improved construction of car .10 coupling of the Janney type and the primary object of the invention is to provide a car coupling of this type :in-wh1ch the knuckle will be pivotally supported without the employment of the usual'pivotor hinge pin now common in suchcouplings.

It a further object of the invention to soconstruct the bearings for the knuckle pin that theknuckle may be readily removed although this is provided for without-weakening the said bearings and withoutthe employment of bolts'or any other means which wouldbe liable to become accidentally disarranged" or loosened.

. Theinvention contemplatesthe provision,

knuckle to the head, of opposedbearmgs, one of'which has an open side closed by a block removably disposed therein and automatically locked.

in place upon insertion. block nor- 80 mally holds the knuckle against removal fromthe drawhead' but when the block is removed, the knuckle may be tilted and re ily. remored'gr dismounted:

n the accompanying drawings,-Figure 85 1 isaperspectiveview ofithe coupling em bodying the features of the' present invention, parts being broken away. Figr 2 is a vertical transverse sectional view through 'the lower bearing for the knuckle: of the- (0 coupling.- Fig. 3is a detailed sectional View disclosing more especially the springcatch 29'. Fig. 4 is a perspective view-10f the removable blo'ck'for closing/o of thebear-- ings for theknuckle ofthe coupling.- Fig.

4515 is a broken sectional elevation showing more especially the knuckle-pivoting studs and adjacent parts.- Fig. 6 is abottom'planview of the upper pivot jaw. Fig.- 7' is a top plan view of the lower pivot jaw.v

In the drawings, there is-shown an -ordinary draw bar 5' carrying adraw. 'head; of the Jimmy type indicated by the numeral- 6. This draw head 6 includes the usual-lateral jaw portion 7 and'at its opposite: side 56 "is formed with spaced bosses the upper one I 'of which is indicated by the numeral 8 and the lower one by the numeral 9. 'The'upper boss 8 is formed witha seat orsocket 10 in its under face and this socket opens solely through this'face of the said an .boss. Ina like manner, the boss 9 is formed -in its upper, face with a socket 11 which opens also through its'side or lateral face which is presented toward the jaw 7. This lateral opening is had by wayof a recess 12 5 formed in the said face of the boss and the vertical walls of this recess are formed with corresponding arcuate grooves 13 as seen in Figs. '1, and 2. A block 14, illustrated in detailin Fig. 4 of the drawings, is designed 7o to close the recess 12 and hence close the lateral opening of thessocketill and this. block is of rectangular general ofifline and is formed at each end with an arcuate rib 15. These ribs 15 correspondin curvature to the grooves 13 and are adapted toseat therein in; the manner illustrated in thedrawings, when the block is in position to close the recess. That face of the block which is-presented inwardly, when the block so -is in position in the recess, is convex as.- clearly-shown in Fig. 2'for a purpose which will presently be explained and in disposing the block in the recess, it is partly rotated about an imaginary center after it. hasbeen so placed-as to-bring .the lowerends of its ribs inthe UPPBIHGIldSOf the grooves. To remove-the block, this operation is-ofcourse reversed. g

The knuckle-of the-coupling is indicated, in general, by the numeral 16 and has the usual nose 17 and tail 18 which-tail will be I presently more specifically referred to. At

"its top and bottom, the .knuckle is formed .w-ith pivot studs 19 and 20 respectii'ely.

The pivot stud 19 is received in the socket lfl 'and the stud 20' is received in the socket 11 and the knuckle is in this manner sup ported for swinging movement on thedraw head. It will be readily understood that the knuckle is assembled with the head by. tilting or cantingit and first engaging'the stud 19in the socket 10. and then rightingv the knuckle to'cause the-stud 20 to enter the socket 11.- The block 14 is then disposed in the recess12-to close the said socket 11. As

a: means for holdingthe blockagainst. accidental displacement, there is provided a springlatch-19' the head 20 of whichi: adapted-to-seatina notch 21-formed in one upper corner of the said block, it being observed that thesaid latch is mounted in one of the'grooves'13 and is so sprung away fromthe wall of the groove that it may be pressedback into the bottom of the groove out of engagement withthe block whereby to permit of removal of the same and subsequent removal of the knuckle.

From the foregoing it will be seen that the invention contemplates a coupling in which the usual pin' for connecting the knuckle with the draw head is dispensed with and a more substantial structure 1S pro- I duced.

ingly, securing said knuckle in locked position. In order to release the knuckle16, an

.upward pull is exerted; upon the chain 26,

which will elevate the block 24'out ofv1en- ,gagement with the tail 18, the stem or pin 22 simultaneously engaging the tail 18 and moving the knuckle 16 into its unlocked position, as indicated in Fig. 1.'

' -1. In a coupling, a

What is claimed is :f 4

draw head having spaced bosses formed each with a socket, one of the bosses being formed 'with a recess communicating with the respective socket, the walls of the recess being formed with vertically disposed grooves, a block removably disposed in the recess and having ribs seating in said grooves, and a knuckle having studs seating in said sockets.

.2. In a coupling a draw head having spaced bosses formed each with. a socket, one of the bosses being formed with a-i'ecess communicating with the respective socket,

the walls of the recess being formed with vertically disposed grooves, a block removably disposed in the recess andhaving ribs seating in said grooves, means locking said block in the recess including a resilient latching member, adapted to engage said block, and a knuckle having studs seating in said sockets. v I

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two-Witnesses.
